Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace outer surface temperature monitoring, in particular to an online blast furnace outer surface temperature monitoring device. Background Art

[0002] The body of the converter / blast furnace includes the furnace shell and the refractory lining inside the furnace shell. The furnace shell is welded with steel plates. The lining includes three parts: the working layer, the permanent layer and the filling layer. The working layer is susceptible to corrosion because it is in direct contact with the liquid metal, slag and furnace body in the furnace. It is generally made of asphalt dolomite bricks or asphalt magnesium bricks in China. The permanent layer is close to the furnace shell and is used to protect the steel plate of the furnace shell. The refractory material of the converter lining has reached its service life. Due to mechanical impact and wear, the high-temperature dissolution of the refractory material and the penetration of the high-temperature solution will cause danger, and the temperature of the furnace shell will gradually increase. Once the working layer and the permanent layer fail, the high-temperature molten steel and molten iron will penetrate the furnace shell, causing the molten steel and molten iron to overflow. More seriously, if the support ring is penetrated, the high-pressure water in the support ring will spray into the furnace, causing a gas explosion. In this process, the state of the working layer can only be observed by naked eyes when the furnace is shut down for maintenance, and accidents can be avoided by manual confirmation. Therefore, it is very necessary to monitor the converter surface temperature online monitoring device online.

[0003] The existing temperature measuring devices have poor measurement uniformity, cannot be quickly disassembled and replaced, and have poor high temperature protection and are unsafe to use.
